Do you want to know if wind power could make sense for you, your business or your community? Do you have the wind resource to live off the grid? Do you have friends/Family that wants to be more ‘green’ and want to explore the variability of wind turbine design and results? Are you looking for a great gift for a person you know that works in the wind industry? Are you simply interested in wind power and want to learn more about the laws of physics associated with it?

The calcWIND 1 graphic calculator is for students, educators, prospective wind power owners, investors in wind projects, community wind groups , and anyone who ever said, "YES!” to any of the above. calcWIND 1 estimates a wind turbine’s cost per kWh and internal rate of return using real-world numbers if you have them ( from a professional wind assessment) and/or your best guesses if you don't.

Multiple methods for analysis

· Get started right away – enter 2 fields and the app will estimate the remaining ones - then run ‘what if’ scenarios
· Enter all 27 fields (the ULTIMATE in control)
· Enter the Turbine’s power curve

Powerful informative Outputs:

· Graphical display outputs including probability distribution, Betz limit, and power
· Operates in your choice of meters/degrees C or feet/degrees F
· Considers costs, the simplified wind regime, and underlying physics to answer ‘what if’ questions

User Help

· Integrated help buttons including “Power Law” and “Derating Factor”
